There is hereby levied and imposed upon all fresh grapes shipped during each marketing season an assessment as fixed by the commission at that amount determined by the commission as reasonably necessary to pay all obligations incurred or to be incurred in accordance with this chapter and as reasonably necessary to carry out the objects and purposes of this chapter. However, during any marketing season the assessment shall not exceed $0.006522 per pound ($0.6522 per 100 pounds), computed on net weight when shipped, whether in bulk or loose in boxes or in any other container or packed in any style package.
All shipments of 150 pounds or less of fresh grapes sold or shipped by a producer direct to the consumer are exempt from the assessments.
